Drawn in conductor cold storage and hot storage apparatus case, and the heat being delivered on semiconductor refrigerating heat-producing machine external heat exchanger, by heat transfer
Onto external heat exchanger, then it is dispersed into the air of surrounding, it is accordingly required in particular to emphasize, because combined type multichannel is narrow flat
Long through-hole 3 and semiconductor refrigerating heat-producing machine external heat exchanger are an entirety, and both the narrow prolate through hole 3 of combined type multichannel was not assembling
To the parts in S types bending liquid coolant flow passage 2, so passing to the heat on semiconductor refrigerating heat-producing machine external heat exchanger
Rapid, accessible, uniform it can be delivered in the metal for the narrow prolate through hole of each bar that heat exchange is carried out with liquid coolant
Wall surface, then the liquid coolant high efficiency by flowing are taken away.
From Fig. 1 and Fig. 2, in the utility model, S types bending liquid coolant flow passage is by least two sections combinations
The narrow combination of prolate through hole 3 of formula multichannel is formed, and covers composition just corresponding to aperture size per the narrow prolate of segments combined multichannel
A round long through-hole of each narrow prolate through hole of bar in through hole 3, both circle long through-hole shown in dotted line in figure, narrow per segments combined multichannel
The sum of girth of cross section of each narrow prolate through hole of bar can be several times as much as this circle long through-hole cross section in narrow prolate through hole 3
Girth, often the sum of area of cross section of each narrow prolate through hole of bar can a phase in the narrow prolate through hole 3 of segments combined multichannel
When the part for justifying long through-hole cross-sectional area in this, if by appropriate design, it is narrow flat per segments combined multichannel
The girth of this circle long through-hole cross section of 3 times of the sum of girth of cross section of each narrow prolate through hole of bar in long through-hole 3, every section
It is long logical to be only equivalent to this circle for the sum of area of cross section of each narrow prolate through hole of bar in the narrow prolate through hole 3 of combined type multichannel
The half of hole cross-sectional area, if the flow of unit interval liquid coolant remains unchanged, with a simply simple circle
Long through-hole compares, and the every segments combined narrow prolate through hole 3 of multichannel formed, liquid coolant are combined by a plurality of narrow prolate through hole
Heat exchange area with metal material is 3 times of this circle long through-hole, and liquid coolant is in the narrow prolate through hole 3 of combined type multichannel
2 times of the flow velocity that flow velocity is liquid coolant in this circle long through-hole, due to flow rate of liquid, to double the then coefficient of heat transfer opposite
0.7 times should be increased, the result is that the heat exchange efficiency of liquid coolant and metal material in per the narrow prolate through hole 3 of segments combined multichannel
It is 5 times of the heat exchange efficiency of liquid coolant and metal material in this corresponding circle long through-hole, the foundation of this conclusion is (1+
0.7) × 3 >=5,1+0.7 represents that flow rate of liquid doubles then when the heat exchange area of liquid coolant and metal material is constant here
The coefficient of heat transfer is corresponding to add 0.7 times, and × 3 are grown because the heat exchange area of liquid coolant and metal material is this circle
3 times of through hole, it is clear that as long as changing design can just make narrow prolate through hole narrower and improve liquid coolant in narrow prolate
Flow velocity in through hole, or increase the quantity of narrow prolate through hole so as to increase liquid while making narrow prolate through hole narrower
The heat exchange area of body refrigerant and metal material, further improves the coefficient of heat transfer of liquid coolant and metal material, improves heat exchange effect
Rate, so the present invention is highly suitable for high-power, the big temperature difference, the needs of High cooling power semiconductor refrigerating heating.
